Narwhals

You may think that narwhals are normal creatures that roam the Arctic, but believe it or not the narwhal population is said to be about 40,000, but all that is changing. Oil and gas is taking over narwhals habitat. Because of more ships in the sea, there are more collisions which will make more noise and that will affect the communication among the the whales causing them to be confused because they can’t hear each other.

Habitat

Different to other species of whale that migrate, narwhals live their lives in the ice cold waters of Canada, Greenland, Norway and Russia. In the winter most narwhals stay under the ice for up to five months in the Baffin Bay-Davis strait area. Narwhals are usually seen in groups of twenty to thirty with different combinations of male, female and calves.

Calves

Narwhals calves are generally born in July and born outside deep bays and channels and stay with the mother narwhal for about twenty months after they are born. Female narwhals are old enough to have their calves at the age of five years and over and males after eight years. Calves are born in the middle of July in the following year (after 15 months of gestation) Female narwhals normally give birth every three years.

Body

Narwhals tusk is said to be an important part of the mating process, because the males have been seen quite a lot, crossing tusks during mating season, as well as using them during over fighting over who's the head of the pod. Narwhals have small round heads. They have short flippers with upturned tips, but they have no flippers on their back.

So now you see why these amazing creatures should live. So stop releasing oil and gas into the ocean so they can live their wonderful lives.
